The steady/pulsatile flow and macromolecular transport in t-bifurcation blood vessels

摘要

A numerical analysis of the steady and pulsatile, macromolecular (such as low density lipopotein (LDL), Albunin) transport in T-bifurcation was proposed. The influence of Reynolds number and mass flow ratio etc. parameters on the velocity field and mass transport were calculated. The computational results predict that the blood flow factors affect the macromolecular distribution and the transport across the wall, it shows that hemodynamic play an important role in the process of atherosclerosis. The LDL and Albumin concentration on the wall varies most greatly in flow bifurcation area where the wall shear stress varies greatly at the branching vessel and the atherosclerosis often appears there.
